Carrillo Replacement Bolts (1 pc.)

Description

The fastener system of a high performance connecting rod is most likely the
most critical unit of the assembly. As a result it is important that the
fastener is installed per instructions and with recommended lube. CP-Carrillo
has close to fifty years of experience of working with what have become the
most recognized fasteners in the connecting rod industry. Much of this has
come from experience which has been tested and validated repeatedly.

Each CP-Carrillo fastener design is based on a known yield load. During linear
stretch of the bolt this load should never be reached. The recommended stretch
value is 80% of yield load calculated in a tension torque diagram.

Torque figures are the more commonly used method for tightening fasteners,
however this is not CP-Carrillo s preferred method. Torque is affected by
numerous variables, all of which can alter the true preload figure you are
trying to attain. Particularly, the lube utilized, the condition of the
threads, the spot face, dimensional integrity, as well as other variables have
an effect. Nearly all of these elements are alleviated if the assembler uses a
stretch method. CP-Carrillo found that the consistency of high quality
fasteners offers the least deviation when using the stretch method, with the
result that the fastener will exhibit proper preload using designated stretch.

CP-Carrillo pays close attention to the above mentioned variables. Dimensional
integrity is foremost — the qualities of the fasteners have set the standard
in the industry and they have continually looked at improved lubrication. The
results of this continued effort is a new, improved lubrication for the
fasteners. This is still molybdenum based lubrication grease, but with
enhanced properties. This product offers an improved clamp load repeatability,
greater resistance to high pressure and temperature (range -22F to 1200F), and
no oil contamination. The coefficient of friction stays unchanged, even after
several bolt re-tightening and loosening processes.

The implementation of this new lube is simply another example of CP-Carrillo s
efforts to continue to offer the finest connecting rod in the industry.
